Abstract:
The embodiments of the present application relate to the field of computer technologies, and disclosed thereby are a data storage method, a storage device, a client and a system. The method is applied to a first storage device of a storage system, and the first storage device comprises a plurality of solid-state drives; the first storage device receives data sent by a client and performs strip virtualization on the data to obtain a plurality of strip data, the data sent by the client being original data written therein; the first storage device encodes the plurality of strip data by means of an elliptic curve (EC) algorithm to obtain EC strip data, the EC strip data comprising a plurality of strip data and check data, and the check data being used for checking the plurality of strip data; and the first storage device caches a plurality of strip data and check data comprised in the EC strip data into a plurality of solid-state drives respectively. Hence, EC strip data may be recovered by means of the EC algorithm when data are lost, thus ensuring the integrity of data storage.
